Berkeley scientist Tyrone Hayes, atrazine, and frogs

Berkeley scientist Tyrone Hayes continues to find remarkable effects of the weed killer atrazine by studying amphibian sexuality. To quote Dr. Hayes from 2002, "I'm not saying it's unsafe for humans. All I'm saying is it makes hermaphrodites of frogs.”

In this NYTimes interview, he says "This paper that we published is — to give you a teaser — nothing. It’s the tip of the iceberg. These are the first two papers of a dozen papers that are long-term looking in incredible depth and detail at the long-term effects of atrazine. We’re looking at homosexuality in frogs, we’re looking at breast cancer, we’re looking at endocrine mechanisms across vertebrates, from fish all the way up to humans."
